WILLIAM E. SHEEHAN, 0F ALBANY, NEW YORK.

PAPER-MAKING MACHINERY.

Specification of Letters Patent.

Patented May 31, 1910.

To all whom it may concern:

Be it known that I, WILLIAM E. SHEEHAN, a citizen of the United States,residing at the city of Albany, in the county of Albany and State of NewYork, have invented certain new and useful Improvements in Paper- MakingMachinery, of which the following is a specification.

My invention relates to paper making machinery, and the object of myinvention is to provide a roll adapted to be used as a couch roll,whereby the water may be quickly and effectively removed from the paperstock brought in contact therewith. I attain this object by means of themechanism illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal elevation partly in section. Fig. 2 is adetail enlarged sectional view. Fig. 3 is an end elevation of myinvention.

Similar letters refer to similar parts throughout the several views.

Upon a cylinder, A, which is provided with perforations, B, I place aseries of rings, C, made of fibrous substance, carded wool preferred.The rings, C, are preferably shrunk on to the cylinder, A, and at eachend of the cylinder I may use a ring, D, of metal, if preferred, for thepurpose of engaging the ring, C, along one edge and a bolt or key, E,fitting in the edge of the cylinder, A, near its end as at I Thecylinder is provided with a suitable axle, G, G, at each end by which itis mounted in the paper machine, not shown. In Figs. 2 and 3 I haveshown the periphery of cylinder, A, with which the felt rings, G, engagecorrugated or provided with a saw-tooth surface, 1-1. As thus arranged Ihave a roll which is elastic, takes the water up more readily than anyother roll with which I am familiar. The water passes out from the feltthrough the passage ways in the core of cylinder, A, and causes the feltto be thus relieved from the presence of the water, which renders itcapable of taking up the water more readily than it would if it became,as is usually the case, water soaked. By arranging the periphery of thecore or cylinder, A, with sawedge projections I provide a flaring mouthto the openings, B, through the core, making a ready exit for the waterfrom the felt.

hat I claim as my invention and desire to secure by Letters Patent is:

1. A roll for use in paper making machinery, comprising a perforatedcylinder; a series of disks of felted fibrous material placed on saidcylinder the surface of said densely felted disks being continuousthroughout its entire extent.

2. In paper making machinery; a roll comprising a perforated core; ahard, densely felted fibrous material placed thereon, whereby is formeda continuous fibrous surface throughout its entire extent and a meansfor drainage and vent into the perforated core through said fibrousmaterial.

3. In paper making machinery; a roll comprising a continuous body ofpromiscuously felted disks of fibrous material pressed to the form of adensely, compact, uniform surfaced mass upon a perforated core.

In testimony whereof I have affixed my signature in presence of twoWitnesses.
